Low FPS clips too fast in VSE
You can setup FPS of the scene in render settings:

But if you have video files with different FPS values in one scene, you can do this:

Add a movie strip with different fps value:



Select Video (not sound) and add Speed Control effect (Shift+A -&gt; Effect Strip -&gt; Speed Control)



By moving end of the strip adjust strip length to be equal sound strip:



Optionaly, you can put all this in meta-strip (by pressing Ctrl+G)


If you haven't sound strip, you can setup Speed Control this way:

Uncheck &quot;Stretch to input strip length&quot;

In Speed factor put {FPS of your file}/{FPS of your scene}




And extend movie clip if it needed
